Magnetic Resonance Microscopy is a technique that entails the application of a radiofrequency (RF) pulse to excite a tissue or specimen at resonance, and the acquisition of signal in the form of RF energy during subsequent relaxation of tissue magnetization. This method provides quantitative parameters that are directly dependent on the tissue properties.

Abstract
Millions of patients experience bone loss as a result of degenerative disease, trauma, or surgery (Xu, Othman, Hong, Peptan, & Magin, 2005). Healthy bone tissue constantly regenerates itself and remodels its architecture to meet the mechanical demands imposed on it, as described by Wolff’s “Law of Bone Remodeling” (Wolff, 1986). However, this capacity is severely limited when there is insufficient blood supply, mechanical instability, or competition with highly proliferating tissues (Pinheiro & Gerbei, 2006). Furthermore, severe bone losses can be detrimental to individuals, because they reduce the bone’s ability to remodel, repair, and regenerate itself (Luo et al., 2005; Nordin & Franklin, 2001), ultimately resulting in the deterioration of a patient’s health, and, in some instances, death (Luo et al., 2005).
